Change mod_wsgi from python3.5 to 3.6

微笑、不失礼 提交于 2019-12-05 13:02:39
I have a flask app that used to run with python3.5 on apache2. I am now trying to change it to run on 3.6 (i have sone type hinting in my code that is only supported on 3.6). I have installed the module for python3.6, but when tried to restart apache and run my app, it fails. When running mod_wsgi-express module-location I have the python3.5 version /usr/local/lib/python3.5/dist-packages/mod_wsgi/server/mod_wsgi-py35.cpython-35m-x86_64-linux-gnu.so The same file also existis on my server in python3.6 dir. I also changed my $PATH to run python3.6 as a default for python. How can I tell apache

Confusion about multiprocessing and workers in Keras fit_generator() with windows 10 in spyder

梦想的初衷 提交于 2019-12-05 11:19:15
In the documentation for fit_generator() (docs: https://keras.io/models/sequential/#fit_generator ) it says that the parameter use_multiprocessing accepts a bool that if set to True allows process-based threading. It also says that the parameter workers is an integer that designates how many process to spin up if using process-based threading. Apparently it defaults to 1 (a single process based thread) and if set to 0 it will execute the generator on the main thread. What I thought this meant was that if use_multiprocessing=True and workers > 0 (let's use 6 for an example) that it would spin

PyCharm and f-strings

狂风中的少年 提交于 2019-12-05 10:38:19
I am using the latest stable PyCharm 2016.1.4 and Python 3.6a1. Whenever I use the "f-strings" ( PEP-498 ) PyCharm is complaining about f being an unresolved reference : Is the literal string interpolation not supported by PyCharm yet? Or, should I have enabled or configured it separately? The Literal String Interpolation is now supported in PyCharm 2016.3 , the relevant feature request: PY-18972 implement support for PEP 498 (f-strings) Note that the stable 3.6 is scheduled to be released in December . 来源: https://stackoverflow.com/questions/38215059/pycharm-and-f-strings

How to call a async function from a synchronized code Python

巧了我就是萌 提交于 2019-12-05 10:18:40
So I'm locked to a python 3.6.2 interpreter that follows my desktop application. What I want is to call an async function from a synchronized method or function. When calling the python function from the desktop application it has to be a normal function which can not be awaited. From the desktop application I am able to send a list of urls, and what I want is to send back response from every url in an async matter. here is my try I've marked the SyntaxError which I don't know how to bypass. import fmeobjects import asyncio import aiohttp import async_timeout logger = fmeobjects.FMELogFile()

Why does inspect return different line for class inheriting from superclass?

不羁的心 提交于 2019-12-05 09:37:07
While trying to figure out if a function is called with the @decorator syntax , we realized that inspect has a different behaviour when looking at a decorated class that inherits from a superclass. The following behaviour was found with CPython 3.6.2 under Windows 10. It was also reproduced in CPython 3.7.0 under Linux 64 bits. import inspect def decorate(f): lines = inspect.stack()[1].code_context print(f.__name__, lines) return f @decorate class Foo: pass @decorate class Bar(dict): pass Output Foo ['@decorate\n'] Bar ['class Bar(dict):\n'] Why does inheritance change the behaviour of inspect

IllegalArgumentException thrown when count and collect function in spark

ⅰ亾dé卋堺 提交于 2019-12-05 07:19:32
I tried to load a small dataset on local Spark when this exception is thrown when I used count() in PySpark ( take() seems working). I tried to search about this issue but got no luck in figuring out why. It seems something is wrong with the partition of RDD. Any ideas? Thank you in advance! sc.stop() sc = SparkContext("local[4]", "temp") testfile1 = sc.textFile(localpath('part-00000-Copy1.xml')) testfile1.filter(lambda x: x.strip().encode('utf-8').startswith(b'<row')).take(1) ## take function seems working and this is what the data looks like: [' <row AcceptedAnswerId="15" AnswerCount="5"

When doing python3 Webhook.py ( this is the file), it gives me the error: File "<fstring>", line 1 (%X - %x) ^ SyntaxError: invalid syntax I've tried to print out the raw contents of the file and I also used a hex editor, there is nothing on line 1 that should be causing erorrs. I also did: import time, os, aiohttp, plistlib, discord, asyncio, json, subprocess In the Terminal.app version of Python3 and I had no errors, my version was 3.6.3 but updated to 3.6.5 to check if the issue would go away, which didn't. Can anyone help? I just spent 1 hour reviewing my code with the same issue. In my
